Exclusion Criteria

  • Hepatitis B surface antigen (HBsAg) positive
  • Hepatitis C antibody positive
  • Individuals experiencing decompensated cirrhosis
  • Females who are breastfeeding
  • Positive serum pregnancy test
  • Have an implanted defibrillator or pacemaker

  • Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to baseline
  • Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the individual unsuitable for the study or unable to comply with dosing requirements

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48Week 48

The percentage of participants achieving HIV-1 RNA \< 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a patient's virologic response status using only the viral load at the predefined time point within an allowed window of time, along with study drug discontinuation status.
